Before the commit "[libgomp, testsuite, openacc] Don't use const int for dimensions", the "const int" construct was used to set launch dimensions in reductions-[1-5].c. In the case of -xc -O0, the const int is implemented as a variable by the C front-end. Consequently, the nvptx back-end generated warnings that vector_length was overridden to be hard-coded, rather than left to be set at runtime. The test-cases silenced these warnings by switching off all warnings in the accelerator compiler using "-foffload=-w". Given that no warnings occur anymore, remove the "-foffload=-w" setting. 2019-01-11 Tom de Vries <tdevries@suse.de> * testsuite/libgomp.oacc-c-c++-common/reduction-1.c: Remove -foffload=-w. * testsuite/libgomp.oacc-c-c++-common/reduction-2.c: Same. * testsuite/libgomp.oacc-c-c++-common/reduction-3.c: Same. * testsuite/libgomp.oacc-c-c++-common/reduction-4.c: Same. * testsuite/libgomp.oacc-c-c++-common/reduction-5.c: Same.
